This is the course work for UVa CS6620, Compiler.
MeggyJava is a programming language based on MiniJava. It can be used to program Meggy Jr RGB, which is a handheld platform for developing your own pixel-scale video games.
This complier will translate MeggyJava code into AVR Assembly, which can be run on the simulator and Meggy Jr RGB device. Also, it will generate a dot file to visualize its AST and Symbol Table.
// using only lexer

// visualize Symbol Table
dot example.ST.dot -Tpng -o example.ST.pngFor example, Test.java has the following AST and Symbol Table:
